I want to update mystatus shell variable to new value inside my awk code. but I guess the syntax isn't right, also I have tried declare or eval , but nothing works hi please help me with this

my code:

   mystatus="resolved" -- shell variable
   awk 'BEGIN { print "<table>" } -- awk code to write in new file
   {
   print "<tr><td>" $1 "</td><td>" $2 "</td><tr>" 
   if ($1=="stopped") mystatus="problem" -- change shell variable value
   }
   END   { print "</table>" }' filestats.txt > email.html
   echo $mystatus -- variabe value not getting changed.

Something like this (untested):

mystatus="resolved"                         # shell variable
awk '
BEGIN { print "<table>" }                   # awk code to write in new file
{
    print "<tr><td>" $1 "</td><td>" $2 "</td><tr>" 
    if ($1=="stopped") {
        mystatus="mystatus.txt"
        print "problem" > mystatus          # write to a file instead
        close(mystatus)
    } # I WAS MISSING I WAS MISSING I WAS MISSING I WAS MISSING I WAS MISSING 
}
END   { print "</table>" }' filestats.txt > email.html
read mystatus < mystatus.txt                # read the status from the file
echo $mystatus                              # variabe value not getting changed.

Some bash purist could comment if this is any way to read from a file to a variable?
